The security of three dimensional (3D) objects has become a hot research area. Efforts were made on the encryption of point clouds, solid models, meshes and 3D textured models. But, for higher and more realistic security, improvements are still needed. Therefore, we improve our previous flexible cryptosystem (FcCA) to fully encrypt 3D textured object with its texture map. Thus, the plain object will extract to: vertices, faces, texture of 3D object and in addition its texture map. Then, encrypt extracted data using improved cryptosystem iFcCA were introduced. Our method shows that it can encrypt and decrypt 3D textured objects and preponderances (FcCA) in all criteria. In addition, the iFcCA can resist different attacks such as: statistic and brute-force, as well as very robustness key. This chapter shall discuss and explain in detail.
